The suspension bushings are essential components of your Buick suspension system. Basically, bushings are made with natural rubber although urethane compounds are used in some cases. Suspension bushings that are made of natural rubber offer excellent tensile strength and outstanding stability at low temperatures. Natural rubber is an elastomeric material which refers to the natural elastic nature of rubber. This allows the movement of the bushing in a twisting plane. Natural rubber bushings do not require lubrication. They are effective in isolating minor vibration, reducing transmitted road shock. Moreover, they operate without being noisy, and offer a large degree of bushing compliance. The control arm bushings are dynamic components of the suspension system which means that they operate while the vehicle is in motion. They act as locators since they hold the position of the suspension in relation to the chassis. They are attached to the vehicle's frame with rubber elastomeric bushings and provide a pivot point for the control arm. They also keep the lateral and vertical location of the control arm pivot points, maintain dynamic wheel alignment as well as reduce transmitted noise, road shock, and vibration, while providing resistance to suspension movement during the suspension travel.
